Description

4-Methylsulfonyl-2,2',3',4',5,5',6-Heptachlorobiphenyl is a highly specific polychlorinated biphenyl (PCB) derivative, distinguished by its methylsulfonyl functional group. This compound is of significant value as a reference standard and analytical standard for environmental and toxicological research. It is primarily needed by analytical laboratories, research institutions, and regulatory bodies involved in the study of PCB metabolites, environmental persistence, and bioaccumulation.

Application

• Environmental Analysis Reference Standard: Used for the calibration and validation of analytical methods (GC-MS, HPLC) to detect and quantify PCB sulfone metabolites in soil, water, and sediment samples.
• Toxicological Research: Serves as a critical reagent in studies investigating the metabolism, distribution, and long-term toxic effects of polychlorinated biphenyls in biological systems.
• Metabolite Identification: Acts as a definitive standard for identifying methylsulfonyl-PCBs, which are key persistent metabolites formed in the environment and living organisms.
• Regulatory Compliance Testing: Employed by testing laboratories to ensure analytical procedures meet regulatory requirements for monitoring persistent organic pollutants (POPs).
• Method Development: Essential for developing and optimizing new chromatographic and spectrometric techniques for the separation and analysis of complex halogenated aromatic compounds.
• Forensic Environmental Chemistry: Used as a marker compound in source identification and fate-transport studies of PCB contamination.
